-
Center beam on all AS optics
-
GET CAMERA IMAGES OF EVERYTHING
- We must get images right before closing, right after closing, etc.
Make sure REFL is clear
- dither PRM, see motion on AP tables
Make sure AS is clear
- dither BS/ITM, see motion on AP tables
Using IPANG/POS pick-off mirrors, center beams on:
IPPOS
IPANG (aligned low in pitch)
Check green alignment in the arms and make sure the transmitted green reaches the PSL table.
-
Check all OpLevs centered, in and out of vacuum
[Jenne, Manasa]
IPANG needed to be re-aligned today. Heavy doors are in place and bolts tight (torque 25 & 45).
Steve! We are ready for pump down!
I will check the IFO alignment once again early tomorrow morning before Steve starts pumping down.
